Re: Need help on Macbook air 1466 with board 820-00165-A. Doesnt turn on

But why if I press the power button, Adaptor shows green then amber.
I check the keyboard rail, if I press the power button, the voltage will become 0V, it means the power button is working.

thx, piernov.

my macbook motherboard model is 820-00165-A.

the problem is before I disassembly it, when I plug in the charger, and the battery is connected, the macbook can not turn on by pressing the power button. If I press the power button, Adaptor shows green then amber.

if I disconnect the battery, plug in the charger, the laptop will automatically turn on and can get into the system. but after I shut down the laptop, can not turn on the laptop by using the power...
